Description

  The present invention relates to a regenerator that regenerates a hygroscopic material used for dehumidifying treatment and a dehumidifying device including the same.

  Conventionally, in a dehumidifying device, a dehumidifying device performs a dehumidifying process for absorbing or adsorbing moisture in the air to a hygroscopic body, and a regenerating unit performs a regenerating process for desorbing moisture from the moisture absorbing body containing water ( For example, see Patent Document 1). For example, in an absorption-type dehumidifier (wet dehumidifier), a hygroscopic liquid is used as a hygroscopic body, and moisture in the air is absorbed by the hygroscopic liquid to dehumidify the air (see, for example, Patent Document 2). . When the hygroscopic liquid is regenerated, the moisture contained in the hygroscopic liquid is released into the air. The dehumidifier and the regenerator are connected by two pipes. The hygroscopic liquid containing a large amount of moisture used for the dehumidifying process in the dehumidifying processor is sent to the regenerator through one pipe. The hygroscopic liquid regenerated by the regenerator is sent from the regenerator to the dehumidifier through another pipe.

  When regenerating the hygroscopic liquid, the hygroscopic liquid is heated to facilitate the desorption of the moisture from the hygroscopic liquid, and the moisture is released into the air by contacting the hygroscopic liquid with air. . As the air used for regenerating the absorbent liquid, outside air existing outside the regenerator is used. At this time, it is desirable that the temperature of the outside air is high. This is because, if the air is hot, the relative humidity is low, and moisture is easily released from the hygroscopic liquid.

  Therefore, it is conceivable to heat the outside air with a heater. However, in this case, such a dedicated heater is required and the cost increases, and energy is consumed to drive the heater. Although it is possible to exchange heat between the exhaust and the intake air by using a heat exchanger and reuse the exhaust heat for the intake outside air, this also increases the cost and the size of the apparatus.

  In addition, it is conceivable to heat the air used for regeneration using exhaust heat from other equipment, but in this case, equipment for transporting exhaust heat from the exhaust heat source is required. This cannot be realized if there is no other equipment.

  Note that there is a similar problem with an adsorption-type dehumidifier (dry dehumidifier). In the case of an adsorption-type dehumidifier, an adsorbent is used as a moisture absorber, air is dehumidified by adsorbing moisture in the air with a dehumidifier, and moisture is desorbed from the adsorber with a regenerator. To regenerate the adsorbent. In the regeneration of this adsorbent, it is desirable to bring high-temperature air into contact with the adsorbent. However, if a dedicated heater is used to raise the temperature of the air, a heater is required as described above, resulting in cost. And the energy to drive the heater is also required.

  The present invention relates to a regenerator capable of supplying high-temperature air to a hygroscopic body to be regenerated without requiring a dedicated heater for heating the air used for regenerating the hygroscopic body, and a dehumidifying device including the regenerator The purpose is to provide.

  The regenerator of the present invention is a regenerator that performs a regeneration process of the moisture absorbent used in the dehumidification process, and a housing that forms a regeneration space in which the regeneration process is performed; An exhaust port for discharging the air used in the casing to the outside of the casing; an inlet port provided in the casing for sucking air used for the regeneration process from the outside of the regenerator; and the exhaust Exhaust guide means for guiding the air discharged from the opening to the outside of the housing so as to flow toward the space in front of the intake opening.

  With this configuration, when air containing a lot of moisture used for regeneration is exhausted from the exhaust port and led to the vicinity of the intake port, the exhausted air releases moisture to the outside air near the intake port. At the same time, it is returned to the regeneration processing space while maintaining a high temperature. Therefore, high-temperature air can be supplied to the intake port without requiring a dedicated heater for heating the air used for the regeneration of the hygroscopic body. Note that the air used for the regeneration process is high temperature and contains a lot of moisture and is humid air. If this highly humid air is used as it is for the regeneration of the hygroscopic body, the release of moisture from the hygroscopic body to the air does not proceed, which is disadvantageous for the regeneration. However, with the above configuration, the exhaust gas exposed to the outside air near the intake port rapidly diffuses the latent heat, and the humidity becomes the same level as the outside air. Therefore, with the above configuration, air having only a high temperature and the same humidity as the outside air is sucked from the intake port and used for regeneration.

  In the regenerator of the present invention, the exhaust port is provided on one surface of the housing, and the intake port is provided on a surface in contact with the surface of the housing where the exhaust port is provided, The guide means is a triangular hood covered by the exhaust port, and guides the air discharged from the exhaust port to rebound by the triangular hood and to flow toward the space in front of the intake port.

  With this configuration, air discharged from the exhaust port can be guided to the vicinity of the intake port with a simple and compact configuration.

  In the regenerator of the present invention, the exhaust port is provided on one surface of the housing, and the intake port is provided on a surface in contact with the surface of the housing where the exhaust port is provided, The guide means is an exhaust chamber provided so as to cover the exhaust port, and the exhaust chamber has a projecting portion projecting from the surface of the housing where the exhaust port is provided, Air is discharged from the portion facing the air intake and is guided to flow toward the space in front of the air intake.

  With this configuration, the air discharged from the exhaust port can be reliably supplied to the vicinity of the intake port with a simple and compact configuration.

  In the regenerator of the present invention, the exhaust guide means is an exhaust duct having one end connected to the exhaust port and the other end opened toward the intake port.

  With this configuration, the air exhausted from the exhaust port can be reliably supplied to the vicinity of the intake port, and when the air is supplied to the vicinity of the intake port, the air is supplied toward the intake port. Efficiency is improved.

  The dehumidifying apparatus of the present invention includes a dehumidifying processor that performs a dehumidifying process of air using a hygroscopic action of a hygroscopic body, the regenerator according to any one of claims 1 to 4, and the dehumidifying processor. A first transport unit that transports a used hygroscopic body to the regenerator; and a second transport unit that transports the hygroscopic body regenerated by the regenerator to the dehumidifier. ing.

  With this configuration, the hygroscopic material can be regenerated by supplying high-temperature air to the regenerating space without requiring a dedicated heater for heating the air used for regenerating the hygroscopic material. .

  The method of the present invention is a method of regenerating a moisture absorber used for dehumidification treatment with a regenerator, and directs the air used for regeneration toward a space in front of the intake port of the regenerator. The moisture absorbing body is regenerated by exhausting to the outside as exhaust, sucking air containing the exhaust from the inlet, and bringing the air sucked from the inlet into contact with the moisture absorber.

  According to this method, when air that has been used for regeneration and has increased in humidity is discharged outside the regenerator, moisture in the air is released to the outside air, resulting in the same level of humidity as the outside air. Air with the same level of humidity is sucked from the intake port while maintaining a high temperature.

  According to the present invention, high-temperature air can be supplied to the intake port without the need for a dedicated heater for heating the air used for regeneration of the hygroscopic body.

The dehumidifying processor 2 includes a housing 21 that forms a dehumidifying space. The housing 21 is provided with an intake port 22 and an exhaust port 23. The intake port 22 includes a fan 221. The dehumidifying processor 2 drives the fan 221 to suck air outside the dehumidifying processor 2 into the dehumidifying space formed by the casing 21 through the air inlet 22. The exhaust port 23 is also provided with a fan 231. The dehumidification processor 2 drives the fan 231 to discharge the air in the dehumidification processing space formed by the housing 21 to the outside of the dehumidification processor 2 through the exhaust port 23. Therefore, air is taken into the dehumidification processing space in the housing 21 from the intake port 22 and is discharged to the outside from the exhaust port 23.

The regenerator 3 drives the fan 321 to suck the air outside the regenerator 3 into the regeneration processing space formed by the casing 31 through the air inlet 32. The exhaust port 33 is also provided with a fan 331. The regenerator 3 drives the fan 331 to discharge the air in the regeneration processing space formed by the casing 31 to the outside of the casing 31 through the exhaust port 33. Therefore, the air is taken into the regeneration processing space in the casing 31 from the intake port 32 and discharged from the exhaust port 33 to the outside of the casing 31.

  A plurality of nozzles 34 for dropping the hygroscopic liquid L are provided inside the housing 31. A holding member 35 for holding the hygroscopic liquid L is provided below the nozzle 34. A liquid tank 36 for storing the hygroscopic liquid L is provided further below the holding member 35. One end of the pipe 5 is connected to the plurality of nozzles 34, and the other end of the pipe 5 is connected to the liquid tank 26 of the dehumidifier 2 described above. In addition, one end of the pipe 4 is connected to the liquid tank 36, and the other end of the pipe 4 is connected to the nozzle 24 of the dehumidifier 2 described above.

  An exhaust guide member 37 that guides the air discharged from the exhaust port 33 to the vicinity of the intake port 32 is provided outside the housing 31 of the regenerator 3. The exhaust guide member 37 is configured as a part of the regenerator 3. The exhaust guide member 37 guides the air discharged from the exhaust port 33 to the outside of the housing 31 so as to flow toward the intake port 32.

  The exhaust guide member 37 has an opening 370 that is open to the outside air so as to intersect with the outside air until the air (exhaust gas) discharged from the exhaust port 33 is sucked from the intake port 32. Thereby, the intake port 32 is also opened to the outside air. The opening 370 of the exhaust guide member 37 is provided in the vicinity of the intake port 32, and the distance between the opening 370 and the intake port 32 is preferably 10 mm to 800 mm, more preferably 50 mm to 300 mm, and still more preferably 80 mm. ~ 200 mm. 1 schematically shows the exhaust guide member 37, the specific configuration of the exhaust guide member 37 will be described in detail later.

  As described above, the liquid tank 36 of the regenerator 3 and the nozzle 24 of the dehumidifier 2 are connected by the pipe 4, and the liquid tank 26 of the dehumidifier 2 and the nozzle 34 of the regenerator 3 are connected by the pipe 5. It is connected. The pipe 4 is provided with a pump 41 for pumping the hygroscopic liquid L stored in the liquid tank 36 through the pipe 4. The pipe 4 is provided with a cooler 42 for cooling the hygroscopic liquid L passing through the pipe 4. The pipe 5 is provided with a pump 51 for pumping the hygroscopic liquid L stored in the liquid tank 26 through the pipe 5. The pipe 5 is provided with a heater 52 for heating the hygroscopic liquid L passing through the pipe 5.

  Operation | movement of the dehumidification apparatus 1 comprised as mentioned above is demonstrated. The dehumidifying apparatus 1 performs dehumidification of air and regeneration of the hygroscopic liquid L by bringing the hygroscopic liquid L and air into gas-liquid contact. In the dehumidification processor 2, a process of dehumidifying the air is performed. When the pump 41 pumps up the hygroscopic liquid L regenerated from the liquid tank 36 of the regenerator 3, the hygroscopic liquid L is cooled through the cooler 42 and supplied to the nozzle 24 of the dehumidifier 2. The hygroscopic liquid L is concentrated by the regenerating process of the regenerator 3 (the water content is low) and is cooled by the cooler 42. Therefore, the concentrated low temperature absorbent liquid L is present in the nozzle 24. Supplied.

  The hygroscopic liquid L is dropped from the nozzle 24 into the dehumidifying space. The hygroscopic liquid L dropped from the nozzle 24 is held by a holding member 25 provided below the nozzle 24, flows downward through the holding member 25, and falls into the liquid tank 26. When the fan 221 at the intake port 22 and the fan 231 at the exhaust port 23 are driven, air flows from the intake port 22 through the holding member 25 toward the exhaust port 23. At this time, the air comes into contact with the hygroscopic liquid L held by the holding member 25. When the concentrated low-temperature hygroscopic liquid L comes into contact with air, the hygroscopic liquid L absorbs moisture in the air. As a result, the air is dehumidified by passing through the holding member 25. The dehumidified air is discharged to the dehumidifying target space outside the housing 21 through the exhaust port 22.

  The hygroscopic liquid L diluted by absorbing moisture in the air is stored in the liquid tank 26. The hygroscopic liquid L in the liquid tank 26 is pumped up by a pump 51 provided in the pipe 5. When the pump 51 pumps up the hygroscopic liquid L, the hygroscopic liquid L is heated through the heater 52 and supplied to the nozzle 34 of the regenerator 3. The hygroscopic liquid L is diluted by the dehumidifying process of the dehumidifying processor 2 (high moisture content) and heated by the heater 52, so that the nozzle 34 has a diluted high-temperature absorbability. Liquid L is supplied.

  The hygroscopic liquid L is dropped from the nozzle 34 into the regeneration processing space. The hygroscopic liquid L dropped from the nozzle 34 is held by a holding member 35 provided below the nozzle 34, flows downward through the holding member 35, and falls into the liquid tank 36. When the fan 321 at the intake port 32 and the fan 331 at the exhaust port 33 are driven, air flows from the intake port 32 through the holding member 35 toward the exhaust port 33. At this time, the air comes into contact with the hygroscopic liquid L held by the holding member 35. When the diluted high-temperature hygroscopic liquid L comes into contact with air, the hygroscopic liquid L releases moisture into the air. As a result, the hygroscopic liquid L is regenerated by passing through the holding member 35.

  The temperature of the air used for regeneration rises due to contact with the high temperature hygroscopic liquid L and heat of vaporization when moisture is absorbed from the hygroscopic liquid L. Accordingly, the air (exhaust gas) discharged to the outside of the housing 31 through the exhaust port 32 is hot and humid.

  The air (exhaust gas) discharged from the exhaust port 32 is guided by the exhaust guide member 37, flows toward the space in front of the intake port 33, is discharged from the opening 370, and is exposed to the outside air near the intake port 33. . Here, the “space in front of the intake port 33” refers to a portion of the space around the housing 31 corresponding to the intake port 33. The exhaust guide member 37 may flow exhaust gas from the direction perpendicular to the opening surface of the intake port 33 toward the space in front of the intake port 33, and from the direction not perpendicular to the opening surface of the intake port 33 to the front of the intake port 33. Exhaust air may flow toward the space.

  When the exhaust is exposed to the outside air, the latent heat diffuses rapidly from the exhaust and the humidity is lowered to the same level as the humidity of the outside air. On the other hand, the sensible heat of the exhaust does not diffuse as rapidly as the latent heat, so the temperature (high temperature) is maintained. Therefore, the intake port 33 sucks in the outside air and sucks such high-temperature exhaust gas that has been discharged from the exhaust port 33 and guided by the exhaust guide member 37. In the regeneration processing space, by bringing such high-temperature air into contact with the diluted high-temperature hygroscopic liquid L, moisture in the hygroscopic liquid L is released into the air. That is, the present invention utilizes the fact that the diffusion rate of vapor is faster than the diffusion rate of temperature, so that only the vapor diffuses into the outside air and the exhaust gas whose temperature is maintained is used as the air for regenerating the hygroscopic liquid L. It is intended to be used as

  Next, the configuration of the exhaust guide member 37 will be described. Hereinafter, three embodiments of the exhaust guide member 37 will be described. However, the exhaust guide member of the present invention is not limited to these embodiments.

(First embodiment of exhaust guide member)
2 and 3 are a perspective view and a cross-sectional view of a regenerator provided with the exhaust guide member of the first embodiment, respectively. The housing 31 of the regenerator 3 is a rectangular parallelepiped, and an exhaust port 32 is provided on the upper surface 311 and an intake port 32 is provided on the front surface 312. A triangular hood 371 as an exhaust guide member is provided above the exhaust port 33. The triangular hood 371 is configured by combining two trapezoidal plate members 3711 and 3712 in a roof shape, and is attached to the housing 31 so as to cover the exhaust port 33. The two plate members 3711 and 3712 are arranged such that a triangular opening 3713 formed with the upper surface of the housing 31 is opened toward the front surface.

  The trapezoidal plate members 3711 and 3712 have the shorter side of the two parallel sides facing each other attached to the casing 31, and the longer side is connected to form a ridge 3714. The front end of the ridge 3714 protrudes before the front surface 312 of the housing 31. Therefore, a triangular opening 3713 formed by the plate members 3711 and 3712 and the upper surface 311 of the housing 31 is opened obliquely downward. The triangular opening on the back side is closed.

  The air discharged from the exhaust port 33 is guided toward the front surface 312 of the housing 31 by the triangular hood 371 and discharged from the opening 3713 obliquely downward. That is, the air discharged from the exhaust port 33 is discharged from the opening 3713 of the triangular hood 371 toward the space in front of the intake port 32, reaches the vicinity of the intake port 32, and enters the regeneration processing space from the intake port 32. Sucked. At this time, when the air exhausted from the opening 3713 is exposed to the outside air, the latent heat is immediately diffused, but the sensible heat is maintained, and the humidity is reduced to the same level as the outside air while maintaining the high temperature. The air is sucked into the air inlet 32.

  Outside air other than exhaust gas is also sucked from the intake port 32 at the same time, but the entire air taken in from the intake port 32 becomes hotter than the outside air. For example, when the temperature of the outside air is 30 ° C. and the absolute humidity is 17 g / kg, the air sucked from the intake port 32 has a temperature of 33 to 35 ° C., and the absolute humidity remains 17 g / kg. . That is, by returning the hot and humid air discharged from the exhaust port 33 to the intake port 32 and sucking it together with the outside air from the intake port 32, the air sucked from the intake port 32 is compared with the outside air itself, Temperature rises by 3-5 ° C and humidity does not rise.

  According to the present embodiment, the exhaust guide member can be realized with a simple and compact configuration called a triangular hood. In addition, an air inlet may be provided on the back surface of the housing 31, and an opening may be formed on the back surface side of the triangular hood.

An exhaust chamber 372 as an exhaust guide member is provided above the exhaust port 33. The exhaust chamber 372 is attached to the upper surface 311 of the housing 31 so as to cover the exhaust port 33. The exhaust chamber 372 is formed in a hollow rectangular parallelepiped shape, and the length in the front-rear direction is longer than the width in the front-rear direction of the upper surface of the housing 31. The portion 3722 is attached to the housing 31 so as to protrude from the front surface 312 and the back surface 313 of the housing 31.

  An exhaust introduction port 3723 is formed on the bottom surface of the exhaust chamber 372 corresponding to the exhaust port 33, and a front surface side opening 3724 and a back surface side opening 3725 are formed on the bottom surface of the front surface side protruding portion 3721 and the back surface side protruding portion 3722. Is formed.

  The air discharged from the exhaust port 33 is introduced into the exhaust chamber 372 from the exhaust introduction port 3723, and part of the air is discharged from the front side opening 3724 toward the space in front of the front side intake port 321, It reaches the vicinity of the intake port 321, is sucked into the regeneration processing space from the front side intake port 321, and part is discharged from the back side opening 3725 toward the space in front of the back side intake port 322, near the back side intake port 322. And is sucked into the regeneration processing space from the back side intake port 322. At this time, when the air exhausted from the front side opening 3723 and the back side opening 3725 is exposed to the outside air, the latent heat is immediately diffused, but the sensible heat is maintained, and the humidity is about the same as the outside air while maintaining the high temperature. The air has been lowered to the front side intake port 321 and the rear side intake port 322, respectively.

  Also in the present embodiment, outside air other than exhaust gas is simultaneously sucked from the front side inlet port 321 and the rear side inlet port 322, but as the entire air taken in from the front side inlet port 321 and the rear side inlet port 322, It becomes hotter than the outside air. Also according to the present embodiment, the exhaust guide member can be realized with a simple and compact configuration.

(Third embodiment of exhaust guide member)

The exhaust guide member of this embodiment is an exhaust duct 373. One end of the exhaust duct 373 is connected to the exhaust port 33, and an opening 3731 is formed at the other end as an open end. The opening 3731 is formed in the vicinity of the air inlet 32 so as to be parallel to the surface of the air inlet 32.
